BEFRIGRATING Ar rnim'izns-l To all whom t may concern.'

Be it known that I, SAMUEL C. CARTY, Va

.Of Washington, in the county of Beaufort and lState of North Carolina, have invented a new and useful Improvement in Refriger atingApparatus, of which the following is a specification.

-My invention relatestoV improvements in refrigerating apparatus', it being directed moreparticularly to an improvedcover for A freezing tanks', and it consistsin the constructions, combinations, andk arrangements herein described and claimed.

vAn object of my invention is to provide a coverfor a freezing tank which is made in sections to cover individual rows of ice cans, so that the cover section of one row of ice cans may be removed, without disturbing the cover sections of the remaining rows 'of ice cans.- 4

Another object of the invention is to provide a cover for a freezing tank which has a central guide ork division strip, the cover for the tank being made in sections to cover individual rows vof ice cans, the purpose of the guide yor ydivision strip of the freezing tank, being .to prevent displacement and over-lap# ping4 of the cover sections.

Another object of my invention is to providefan auxiliary cover for theV ice cans in av freezing tank by which the insulating qualities of the ice can tops are supplemented with a corresponding increase in the etliciency of the yfreezing tank. I

Other objects and advantages will appear in the following specification, reference being had to the accompanying drawing in whichif .l Figure l is aplan view ofa portionof a `freezing tank showing the improved cover sections applied thereto,'two' of the cover sections beingfshownfremoved to reveal the ice cans beneath. y

ples 5 by which the sections of the covers The cover sections 3 and 4 resty in recesses G formed by rabbeting the inside upper edges of the sides 7 of a freezing tank, as shown in x Fig. 1. The cover sections 3 and 4'also rest in recesses 8 formed by rabbeting the upper edges of a'centraly guidejor divisionstrip 9.

The freezing tank shown in Fig. 2, also in cludes the end wall 10 and bottom v11. YThe walls of the freezing tank are box-like structures'of a suitable material, and are filled with an' insulating material as indicated at Y 12 in Fig. 2, which may consist of cork, mineral Wool, etc. It will be observed more particularly in Figs. 2 and 3, that the provision of the cover section recesses 6 and 8 in the side-walls and the guide stripsv 9, makes it possible for the top surfaces ofthe covers 1 and 2 to come Hush with thev npper edgesV of the respective walls of the freezing tank.

A plurality of ice cans 13 which havetops 14 are located in the freezing tank at either side of the'guide stripY 9. In the present arrangement, the ice cans 13 are `arranged in transverse rows of seven cans each on the left side of the guideV strip 9, and intransverse rows of eight;v cans each onl the righty side of the guide strip 9. There are also seventeen (17) individual rows of cansyrunning lengthwise of the freezing tank, and it will beJ readily understood fromthe above Ytaken'in connection with Fig. 1, that thirtyfour (34) of the cover sections 3 and 4 will be necessaryto completely cover all of the cans 13 in the freezing tank. The covers 14 of the freezing cans 13, ordinarily are the only means for insulating the ice'in the cans from the lheat in the atmosphere outside. The cover lsections3v and 4 of the'covers l lating qualities ofthe can tops 14, and when in place as shown in Fig. 2, virtually form rranother wall for the freezing tank which is .equal in thiclmess and in all otherrespects,

to the remaining wall'sof the freezing tank. With regard to the construction of the cover sections 3 and 4, reference is directed to Figs. 2 and 3.

Each cover section includes a'pair of vertically arranged boards .15, which are spaced apart by abottom board 16, and taken in connection with a top board 17, form a box-like structure in which insulating material 18 may be packed. The boxklike structure of eachcover section is,

furthermore, provided with transverse inand 2 are designed to supplement theinsusert pieces 19, as; shown in Fig. 2. series of `compartments is thus really formed, 1n

which the insulating material 18is. packed.

The pieces 19 also form braces for the 5 relatively long cover sections, andobviously the sides are prevented from bulging by said strips when packing the insulating inaterial in place. Referring again to Fig. 3,

it will be seen that the cover board 17 does not squarely cover the cover section, but'is off-set so that one edge of the cover board 17 vextends beyond- Yone of the side boards 15, while the other edge of the top board 17 is correspondingly spaced from the outer surface of the other side board 15. y It will be evident that this construction provides a flange 17 a at one side, and a recess 1'7b at the other. It vwill also be understood that the fiange 17a of one cover section,'will fit into 20 vthe recess 17b of the companion cover section, and thus when all ofthe sections are in place, unitary cover is provided. The provision of the anges 17 a, also makes it necessary to provide a recess r17c in the upper,

. inner edge of the end wall 10.

The application and operation of the improved cover is as follows: The freezing tank shown in the drawing Yis of any ordinaryI construction, and no change is made in the tank to accommodate the Aimproved cover, excepting to provide the division strip 9 in substantially the center of the tank,Y

which is adapted to keep the cover-sections v from lapping by veach other, and it also makes it more easy to shift the cover sections from one row of cans to the other as will presently be explained. u lj Incidentally, the coversectionsv may be made oftongue and grooved boards, or ofV ship lap stuff, cork or other insulating inaterial being packed therebetween as pre-K viously set forth. It will beunderstood, of

, course, that the actual materials ofi-which thesections are made and the mode of constructing them, camiot be fully set yforth f here, since this is a matter which is best regulated in the manufacture of the cover sections.

Resuming the operation of the device, the

cans 13 are filled with water after'having been arranged in suitable rows in the freezing tank, andthe can covers 14: put in place. Ordinarily the can covers Vare the only insulating means in` addition to the walls of the freezing tank. kThe cover sections 3 and l of the auxiliary covers 1 and 2 are then apvplied to the freezing tank. The cover sections rest in the recesses 6 and Sjin the sidev walls 7 of the freezing tank, and of the guide strip 9, respectively. l`One cover section f covers a single transverse rowrof cans on either side of the guide strip 9. The Water in the ice-cans 13 is then frozenrinto ice.

Now, in the operation of the device, all of the cover sections 3 and 4 are put in place excepting two cover sections at one end of 'the freezing tank. The' act of removing the cakesof icenow commences. Beginning at one of the rows of cans represented A in F ig.,3', the cover section is removed from over the row of cans and is slider carried'to the opposite end where there is no cover section, as just stated. The icein the row of cans 13 thus exposed, is .pulled out and the cans are kre-illed with water.

The next cover section B in Fig. 3, is then slid ahead and replaces the cover section A previously removed. The ice in the cans 13 exposed by removing the cover section B, is then pulled and the 'cans are re-illed with water. The next cover section is then slid forwardly, leaving a vacant space indicated C in Fig. 3. The ice from the exposed cans is pulled, and each step as just enumerated, is repeated throughout the entire length of each section of the freezing tank until all of the cakes of ice are removed. It will be thus understood'that after one cover section is removed, the remaining'cover sections are simfply slid ahead the width'of one cover section.

Thus only one row of cans is exposed at a time and the obvious benefit of this-arrangementis, that all of the cans are not exposed to the heat of the atmosphere, with-the consequent saving inv ice.

In conclusion it may be stated that my improved insulating cover is not connedin use alone to refrigerating apparatus, as described, but may also be used in a furnace to r`prevent the undesired escapeof heat. It

*may also be applied'vvherever it be desired Vto stop the inflow oroutflow of heat or cold. 1Thecoversectionsmay have joints of elasticmaterial 20, so arranged to makethe cover practicallyair tight. As'shown'in Fig. 4, 'the elasticmaterial is applied to the sides of the sections and in the joi1`1ts,'sok

that when thesections are pressed together, the elastic material will become compressed and thus form the air tight joint referred to.

Vhile theconstruction and arrangement of the device as illustratedin the accompanying drawing is that'of a generally preers for the tank, each 'consistingiof a plurality of closed box-like sections fille'd'with insulating material and each havingits top projecting beyondone "side wall andterminating approximately at the outer end of in the recesses from one row to another, theV division strip forming a guide preventing the overlappingk of the cover sections during the shifting of said sectlons.

2. In a freezing tank, a cover consisting s of elongated sections adapted to be disposed over rows of cans, each section including side and bottoin boards, transverse pieces forming braces for the elongated sections, insulating material packed in the spaces between said boards and the transverse pieces, a top board having one edge projecting beyond one of the side boards to form a flange, and the other edge spaced in from the other side board to form a recess, the flanges and recesses of companion cover sections interengaging when the cover is in place, and handles carried by the cover sections.

3. In a freezing tank including a side wall having a longitudinally rabbeted edge, a

partition having a companion longitudinally rabbeted edge, a cover adapted to rest in the recesses formed by said rabbets, said cover being composed of sections slidable in said recess, top and side boards included in each section, one edge of the top board projecting beyond one edge of one side board to form a flange, the other edge of the top board being spaced in from the other side board to form a recess, and an elastic material applied to the sides and said edges of the sections, to form an air tight joint when the sections are shifted into contact.

4. A cover fr freezing tanks, consisting of a plurality of closed box-like sections lled with insulating material, the top of each section having one edge projecting beyond one side wall of the section and its opposite edge terminating short of the outer face of the opposing side wall yof the said section.
